Description

Water tank for fire suppression {FIRE EXTINGUISHING WATER TANK}

The present invention relates to a water tank for fire suppression.

As the spread of electric vehicles expands, research is being conducted on technology to extinguish fires occurring in electric vehicles. Batteries such as lithium-ion batteries are widely used as a means of supplying power to electric vehicles. If the temperature inside the battery rises due to a fire around the battery, the battery separator may be deformed or damaged, causing a direct short circuit between the positive and negative electrodes of the battery. A direct short circuit between the anode and cathode causes an explosive exothermic reaction, which further increases the temperature of the battery and promotes a fire. Additionally, when the temperature of the battery rises, some of the active materials in the anode or cathode are decomposed and oxygen is generated, further promoting ignition and combustion in the battery or its surroundings. In this way, additional heat and oxygen are generated due to an increase in the temperature of the battery, which further promotes a fire, which is called thermal runaway.

Since the thermal runaway of a battery continues until all of the internal energy of the battery is used up, it is difficult to extinguish a fire in a battery using general fire extinguishing equipment. A known method of extinguishing a battery fire is to cool the battery and prevent thermal runaway of the battery. Specifically, since the batteries of electric vehicles are usually placed at the bottom of the electric vehicle, research has been conducted on a method to prevent the temperature of the battery from rising and block oxygen by forming a water tank around the electric vehicle so that the lower part of the electric vehicle is submerged in extinguishing material in the event of an electric vehicle fire. It is becoming.

Figure 1 shows a plan view of a water tank (1) for fire suppression according to the present invention surrounding a fire-fighting object (5). In addition, Figure 2 is a diagram conceptually showing a cross section of a water tank 1 for fire suppression according to an embodiment of the present invention. Specifically, FIG. 2 shows a cross-sectional view of the fire suppression water tank 1 shown in FIG. 1 cut along plane AA'.

In one embodiment, the water tank 1 for fire suppression extends in the longitudinal direction to form a closed loop, and as the first fluid is supplied to the main fluid chamber 15 inside and expands, it is flush with the ground. The main tube 10 forming the space 90 for receiving extinguishing substances is disposed adjacent to the main tube 10 so that at least a portion is fixed to the main tube 10, and is disposed along the longitudinal direction of the main tube 10. A guide fluid chamber 25 is formed inside, and the guide tube 20 expands the main tube 10 as the second fluid is supplied to the guide fluid chamber 25 and expands, and the outer peripheral surface of the guide tube 20 It may include a guide fluid chamber input port (port) 30 disposed in and communicating with the guide fluid chamber 25.

In one embodiment, the main tube 10 may extend in the longitudinal direction to form a rectangular closed loop. Each side of the rectangular main tube 10 can be set to correspond to the shape and size of the vehicle. When the fire suppression water tank (1) according to the present invention is used to extinguish a fire that occurs in a vehicle such as an electric car, the fire suppression water tank (1) can be deployed without restrictions in narrow spaces such as parking lots or in open outdoor spaces. There is an advantage.

The fire suppression tank 1 may be stored folded or rolled up before being deployed. Specifically, the main tube 10 or the guide tube 20 may be stored folded or rolled before being deployed. The guide fluid chamber 25 is formed inside the guide tube 20, and a second fluid is supplied to the guide fluid chamber 25 to expand the guide tube 20. The second fluid may be a liquid or gas with low density. This helps the guide tube 20 to expand quickly by quickly supplying the second fluid to the guide fluid chamber 25. In one embodiment, the guide fluid chamber 25 may complete inflation in approximately 2-3 minutes.

The guide fluid chamber 25 may be arranged along the longitudinal direction of the main tube 10. For example, the guide tube 20 may be arranged to be fixed to the main tube 10 along the longitudinal direction of the main tube 10. This helps the folded or wound main tube 10 to expand to correspond to the shape of the guide tube 20 that expands as the second fluid is supplied to the guide fluid chamber 25. That is, the guide tube 20 can induce the expansion of the main tube 10.

In one embodiment, before the first fluid (e.g., fire water) is supplied to the main fluid chamber 15 inside the main tube 10, the second fluid (e.g., gas) is supplied to the guide fluid chamber 25. The main tube 10 may be expanded by the guide tube 20, which expands as it expands. The guide tube 20 to which the second fluid is supplied to the guide fluid chamber 25 is tightly expanded by the pressure of the second fluid and may function like a frame. That is, with the help of the guide tube 20 that is tightly expanded like a frame, it can be easy to properly position the fire suppression water tank 1 around the firefighting object 5. For example, the user passes one side of the fire suppression tank (1) over the fire extinguishing object (5) using the tensioned guide tube (20) inside the closed loop (preferably in the closed loop) of the fire suppression tank (1). The fire suppression tank (1) can be positioned so that the fire-fighting object (5) is located near the center of. This means that when the second fluid has a relatively lower density than the first fluid, the case where the second fluid is supplied to the guide fluid chamber 25 expands lighter and faster than when the first fluid is supplied to the main fluid chamber 15. Therefore, it has the advantage of being able to quickly and conveniently position the fire extinguishing water tank (1) at an appropriate location around the fire-fighting object (5) without supplying the first fluid. After the fire suppression water tank 1 is placed at an appropriate location around the fire-fighting object 5, the first fluid may be supplied to the main fluid chamber 15 to form a space 90 for containing the fire extinguishing material.

In one embodiment, the water tank 1 for fire suppression may include main fluid chamber input ports 11 and 12 disposed on the outer peripheral surface of the main tube 10 and communicating with the main fluid chamber 15. For example, a fire hose may be connected to the first main fluid chamber input port 11 to supply the first fluid to the main fluid chamber 15. Alternatively, the first fluid source may be connected to the second main fluid chamber input port 12 and the first fluid may be supplied to the main fluid chamber 15 through the second main fluid chamber input port 12. The second main fluid chamber input port 12 may include a single-stage ball valve. The first fluid source may supply tap water to the second main fluid chamber input port 12 through a general hose. In one embodiment, expansion of the main fluid chamber 15 can be completed within about 10-15 minutes through the first main fluid chamber input port 11. However, the expansion time may vary depending on whether the second main fluid chamber input port 12 is simultaneously used.

In one embodiment, the water tank 1 for fire suppression may include a main fluid chamber output port 19 disposed on the receiving space 90 side of the main tube 10 and communicating with the main fluid chamber 15. there is. While the main tube 10 is being expanded or after the expansion of the main tube 10 is completed, at least a portion of the first fluid filled in the main fluid chamber 15 is supplied to the receiving space through the main fluid chamber output port 19. 90) can be sprayed. This has the advantage of filling the accommodation space 90 more quickly. Or, while the main tube 10 is being expanded or after the expansion of the main tube 10 is completed, at least a portion of the first fluid filled in the main fluid chamber 15 is transferred to the fire-fighting object through the main fluid chamber output port 19. (5) It can be sprayed directly. This helps to extinguish the fire of the fire-fighting object (5) more quickly. In this case, the fire extinguishing material filled in the receiving space 90 and the first fluid may be the same.

In one embodiment, the water tank 1 for fire suppression may include a main fluid chamber drain port 13 that communicates with the main fluid chamber 15. The main fluid chamber drain port 13 may be disposed on the outer peripheral surface opposite the receiving space 90 of the main fluid chamber 15. The first fluid may be drained from the main fluid chamber through the main fluid chamber drain port 13.

In one embodiment, the first fluid and the second fluid may be different. Specifically, the first fluid supplied to the main fluid chamber 15 may be a liquid with a relatively higher density than the second fluid. For example, the first fluid may be a liquid and the second fluid may be a gas. More specifically, the first fluid may be fire water, and the second fluid may be high-pressure gas contained in the container 8. This helps the fire suppression water tank 1 to be brought into close contact with the ground by the load of the first fluid.

In one embodiment, the main tube 10 may be positioned between the ground and the guide tube 20. More specifically, the guide tube 20 may be stacked and arranged on the main tube 10. For example, the main tube 10 through which the first fluid is supplied to the main fluid chamber 15 may be heavier than the guide tube 20 through which the second fluid is supplied into the guide fluid chamber 25. In this case, the main tube 10 is placed below the guide tube 20 so that the center of gravity of the fire suppression tank 1 is closer to the ground, so the fire suppression tank 1 can maintain its shape stably.

The diameter of the main tube 10 or the main fluid chamber 15 may be larger than the diameter of the guide tube 20 or the guide fluid chamber 25 disposed on the main tube 10. In addition, the center of the cross section of the main tube 10 or the main fluid chamber 15 may overlap in the vertical direction with the center of the cross section of the guide tube 20 or the guide fluid chamber 25 disposed on the main tube 10. there is. This has the advantage of preventing the guide tube 20 from deviating laterally from the main tube 10 by stably seating it on the main tube 10.

In one embodiment, the second fluid may be supplied to the guide fluid chamber 25 through the guide fluid chamber input port 30 that communicates with the guide fluid chamber 25. The guide fluid chamber input port 30 may include a valve 31, a hose 32, a receptor 33, or a combination thereof. The flow rate of the second fluid supplied to the guide fluid chamber 25 through the guide fluid chamber input port 30 may be adjusted by the valve 31.

In one embodiment, the guide fluid chamber input port 30 may be in communication with a second fluid source. For example, the guide fluid chamber input port 30 may be in communication with the container 8 containing the second fluid. The vessel 8 may contain a compressed second fluid. For example, the vessel 8 may contain high-pressure gas. By containing the compressed second fluid in the container 8, the volume of the container 8 can be made smaller, and the container 8 can be easily carried along with the water tank 1 for fire suppression. Additionally, the second fluid compressed in the container 8 can be quickly supplied to the guide fluid chamber 25. In the present invention, the second fluid source is not limited to the container 8. For example, the second fluid source may include a source such as a fluid pump.

In one embodiment, the water tank 1 for fire suppression opens the container 8 containing the compressed second fluid so that the contained second fluid enters the guide fluid chamber 25 through the guide fluid chamber input port 30. It may further include a fluid injection device (100, 200) in communication with the guide fluid chamber input port (30) so that the fluid can be supplied to the guide fluid chamber input port (30). The fluid injection devices 100 and 200 will be described in detail later with reference to FIGS. 9 to 11 .

The guide fluid chamber input port 30 may include a hose 32 and a receptor 33. The receptor 33 may be directly connected to the second fluid source, or may be indirectly connected to the second fluid source by being connected to another member in communication with the second fluid source. The receptor 33 may be connected to one end of the hose 32, and the valve 31 may be connected to the other end of the hose 32. The receptor 33 can be separated from the fire suppression tank 1 by the hose 32 extending in a direction away from the fire suppression tank 1, and the user can more safely connect the receptor 33 to the second fluid source. There is an advantage in being able to connect.

In one embodiment, the receptor 33 may have a structure corresponding to that of a firefighter's air respirator. Specifically, a firefighter's air respirator may be connected to the receptor 33, and air may be supplied to the guide fluid chamber 25 through the receptor 33.

In one embodiment, the fire suppression water tank 1 is disposed on one side of the guide tube 20 and is opened when the internal pressure of the guide fluid chamber 25 is higher than a preset pressure to adjust the guide fluid chamber 25. It may further include a safety valve (29). Specifically, when the internal pressure of the guide fluid chamber 25 is higher than a preset pressure, the safety valve 29 is opened and the second fluid inside the guide fluid chamber 25 may flow out of the guide tube 20. At this time, a sound may be heard, through which it can be confirmed whether the internal pressure of the guide fluid chamber 25 is higher than a preset pressure. This has the advantage of preventing damage to the guide tube 20 due to excessive internal pressure being applied to the guide fluid chamber 25.

In one embodiment, the safety valve 29 may be disposed on the outer peripheral surface of the guide tube 20 on the opposite side from the guide fluid chamber input port 30 with the accommodation space 90 therebetween. Specifically, the safety valve 29 may be disposed on the outer peripheral surface of the guide tube 20 at the furthest distance in the horizontal direction from the guide fluid chamber input port 30. This is because sufficient second fluid is not supplied to the guide fluid chamber 25, and the local pressure near the safety valve 29 increases even though the guide tube 20 is not yet sufficiently expanded, causing the safety valve 29 to open and allow the second fluid to flow. There is an advantage in preventing the expansion of the guide tube 20 from being delayed due to leakage to the outside.

The extinguishing material may be supplied to the receiving space 90 inside the closed curve of the main tube 10. The main tube 10 or the guide tube 20 may form a side wall to prevent the fire extinguishing material supplied to the accommodation space 90 from leaking out of the accommodation space 90. At this time, the gap between any two of the main tube 10, the guide tube 20, and the ground will be partially or fully filled by the load of the main tube 10 or the guide tube 20 or by a separate sealing member. You can. The sealing member may be made of the same material as the main tube 10 or the guide tube 20 or may be made of a different material.

In one embodiment, the water tank 1 for fire suppression is formed on the outer peripheral surface of the main tube 10 so that the base end 41 is pressed against the ground by the load of the main tube 10, and the distal end 42 is at least partially It may further include a main flap 40 that contacts the ground and extends toward the receiving space 90. For example, the proximal end 41 of the main flap 40 may be formed at the lower end of the main tube 40. A portion of the main flap 40, for example the proximal end 41 and/or the distal end 42, is subject to the load of the first fluid filled in the main tube 10 or the load of the fire extinguishing material filled inside the receiving space 90. It can be pressed to the ground by . The main flap 40 may limit the leakage of extinguishing substances in the accommodation space 90 through the gap between the ground and the fire suppression tank 1.

The fire suppression tank 1 may further include at least one flap in addition to the main flap 40. That is, in one embodiment, the fire extinguishing water tank 1 has a proximal end 46 formed on the surface of the main flap 40 so as to be pressed against the ground by the load of the main tube 10, and at least the distal end 47. It further includes a sub flap 45, a portion of which is in contact with the ground, and the sub flap 45 may be disposed between the ground and the main flap 40. Specifically, the proximal end 46 of the sub flap 45 may be disposed closer to the ground than the proximal end 41 of the main flap 40, as shown in FIG. 2 . For example, the proximal end 46 of the sub flap 45 is disposed between the main tube 10 and the ground, so that the proximal end 46 may be pressed against the ground by the load of the main tube 10. The sub flap 45 may limit the leakage of the fire extinguishing material in the receiving space 90 through the gap between the main flap 40 and the ground.

In one embodiment, an additional metal ball or iron bar, etc. may be fixed to the end of the main flap 40 or the sub flap 45. In another embodiment, a member made of a material that expands when absorbing water may be attached to the end of the main flap 40 or the sub flap 45. Through these embodiments, it is possible to further prevent the extinguishing material in the accommodation space 90 from leaking below the water tank 1 for fire suppression.

In one embodiment, at least a portion of the fire suppression tank 1 may be flame retardant or may include a flame retardant material. The flame retardant material may include Kevlar fabric. For example, at least a portion of the main tube 10 or the guide tube 20 may be flame retardant or may include a flame retardant material. Specifically, the outer peripheral surface of the main tube 10 or the guide tube 20 on the receiving space 90 side may be flame retardant treated or made of a flame retardant material. This has the advantage of preventing damage to the fire suppression water tank (1) by resisting fire or high temperatures well.

In one embodiment, the water tank 1 for fire suppression may further include a cover 51 that covers at least a portion of the outer peripheral surface of the main tube 10 or the guide tube 20 on the receiving space 90 side. Specifically, the cover 51 has a proximal end 51a disposed at the upper end of the fire suppression water tank 1 (e.g., the upper end of the guide tube), and is arranged along the outer surface of the fire suppression water tank 1 from the proximal end 51a. It may extend downward toward the accommodation space 90 of the fire suppression tank 1 and cover at least a portion of the main tube 10 or the guide tube 20. The distal end 51b of the cover 51 may cover at least a portion of the main tube 10. The cover 51 can protect the fire suppression water tank 1, especially the main tube 10 or the guide tube 20, from fire on the accommodation space 90 side. Additionally, the cover 51 can help the fire extinguishing water tank 1 withstand the pressure of the extinguishing material cold in the receiving space 90.

In one embodiment, the cover 51 may cover the gap 60 between the main tube 10 and the guide tube 20. This has the advantage of limiting the extinguishing material supplied to the accommodation space 90 from leaking from the accommodation space 90 into the gap 60 between the main tube 10 and the guide tube 20.

In one embodiment, the water tank 1 for fire suppression may further include a connection part that opens or closes a loop formed in the longitudinal direction of the main tube 10. Specifically, when the loop formed in the longitudinal direction of the main tube 10 is opened, both open sides can be defined as one end and the other end, respectively. When one end and the other end are connected to each other, the main tube 10 can form a closed loop. A connecting portion including a fastening member may be provided at either one end or the other end so that the one end and the other end are connected to each other and fixed to each other. Alternatively, a connection portion including corresponding fastening members may be provided at each one end or the other end. For example, the connection may include a waterproof zipper.

In this case, one end and the other end of the main tube 10 are connected to each other by a connection part, so that the main tube 10 can form a closed loop. One end of the main tube 10 may be placed near the fire-fighting object 5, and the other end of the main tube 10 may be disposed so that the 'C'-shaped main tube 10 surrounds the fire-fighting object 5. Can be placed near the fire-fighting object (5). Then, one end and the other end of the main tube 10 are connected to each other through the connection part, so that a closed loop of the main tube 10 can be formed. This has the advantage of allowing the main tube 10 to form a closed loop surrounding the fire-fighting object 5 without the user having to pass the main tube 10 over the fire-fighting object 5.

Figure 3 is a diagram conceptually showing a cross section of a water tank 1 for fire suppression according to another embodiment of the present invention. In one embodiment, the main fluid chamber 15 or the guide fluid chamber 25 may have a multi-compartment structure. Specifically, the main fluid chamber 15 or the guide fluid chamber 25 may include an outer compartment and an inner compartment disposed between the outer compartment and the receiving space.

According to FIG. 3, the main fluid chamber 15 is divided by a first partition 16a and a second partition 16b, and the main fluid chamber 15 includes an outer compartment 15c and a first inner compartment 15a. And a second inner compartment 15b may be included. In this case, even if the side wall on the receiving space 90 side of the first inner compartment 15a is damaged, the main tube 10 can still maintain a closed loop shape due to the second inner compartment 15b and the outer compartment 15c. It is possible to prevent a problem in which the receiving space 90 is destroyed and the extinguishing material is no longer accommodated in the receiving space 90 . In addition, even if the first partition 16a is damaged, the main tube 10 can still maintain a closed loop shape due to the outer compartment 15c.

According to FIG. 3, the guide fluid chamber 25 is divided by a partition wall 26a, and the guide fluid chamber 25 may include an outer compartment 25b and an inner compartment 15a. In this case, even if the side wall of the first inner compartment 15a on the accommodation space 90 side is damaged, the guide tube 20 can still maintain its shape due to the outer compartment 25b.

Each of the partition walls 16, 17, and 26 that divide each fluid chamber to form a compartment may include backflow prevention structures 16a, 17a, and 26a.
